The ATI has a 12V trigger, it is just that funky one that alot of receivers and pre/pros don't have. I think there was a thread on here, or the old place where Soundhound explained how to make it work.
If not I found a simple solution. I have a Monster Power Center, don't poke fun I got it CHEAP, and I hooked up my 1505 to the "switched" outlet on my power center. When I am ready to use it, I turn the switch on the power center on and VOILA my amp comes on. When I shut everything else down via my Harmony, I simply walk over and redock my Harmony and push the switch on my power center to off.
Now, the only thing in standby mode and drawing any current at all is my power center.
